Tomorrow we’re holding our annual Cheap Tramadol Uk. This year we’ve decided to stream the entire event on both YouTube and Facebook using binaural audio (well, Ambisonics to binaural as it happens). The event is 9.30am (GMT+1) until around 5.00pm. If you’re interested in watching the events, here’s the links:

EDIT: You can download a Cheap Tramadol Fedex Overnight (for Reaper) that does the conversion from ambiX to TBE and another that goes from TBE to 2nd order, 2D, Furse-Malham format here (I’ve included my remapping JS effect too, so you can also go from Furse-Malham to TBE format by converting to that first 🙂 :

Facebook have updated TBE to remove the ‘R’ component from channel 4. This is important as, before it was removed, it was impossible to go from TBE to 1st order Ambisonics (for Youtube etc.). The new details are excellently discussed on Angelo’s webpage which can be found at Cheapest Tramadol Overnight

Angelo Farina has published an excellent article detailing how the 9, 2nd order Ambisonic components map to the 8 channels of the Facebook360 TBE format (they decided to pander to the 8-channel limit of pro-tools 🙁 ). All the details can be found at Angelo’s website:

I’ve had a few people ask for me to share the animations from my Surround Audio for VR presentation that I delivered at Ordering Tramadol Online Forum this year. I’ve made a video of the powerpoint (30 seconds per slide) so everything can be viewed in context (note there’s no audio, though!). If you weren’t at the event, it goes through both the graphics and audio processing needed to create VR content and shows the limitations, with respect to the inter-aural level (ILD) and time (ITD) differences reproduced by the Ambisonics to Binaural process at varying orders. 8th order Ambisonics does a great job reproducing both the ILD and ITD up to 4kHz.

UPDATE : 4th May 2016 – I’ve added a video using the measured filters. This will be useful for auditioning the mixes before uploading them to YouTube.

So, I’ve been experimenting with YouTube’s Ambisonic to Binaural VR videos. They work, sound spacious and head tracking also functions (although there seems to be some lag, compared to the video – at least on my Sony Z3), but I thought I’d have a dig around and test how they’re implementing it to see what compromises they’ve made for mobile devices (as the localisation could be sharper…)

Cut to the chase – YouTube are using short, anechoic Head Related Transfer Functions that also assume that the head is symmetrical. Doing this means you can boil down the Ambisonics to Binaural algorithm to just four short Finite Impulse Response Filters that need convolving in real-time with the B-Format channels (W, X, Y & Z in Furse Malham/SoundField notation – I know YouTube uses ambiX, but I’m sticking with this for now!). These optimisations are likely needed to make the algorithm work on more mobile phones.

So, last week Overnight Tramadol Visa. Ambisonics is now one of the defacto standards for VR audio. This is a big moment! I’ve been playing a little with some of the command line tools needed to get this to work, and also with using Google PhotoSphere pics as the video as, currently, I don’t have access to a proper 360 degree camera. You’ll end up with something like this:

I’ve recompiled all the plug-ins so there are now 64-bit versions of WigWare for those who now use 64-bit hosts. All audio processing is un-changed. Several issues with the Mac graphical user interface occurred when switching to 64-bit (nothing had to change on Windows!) which I had to fix, so please let me know if there are any issues! Downloads are on the Purchasing Tramadol page, or below :

Sounds in Space happened on 30th June this year and was an excellent day (the programme and details of the day can be found Tramadol Rx Purchase). There are always things which could be done better, and hopefully we’ve got all these noted ready for next year (fingers crossed). If you weren’t able to make the event, then the details below may give you a glimpse of what you missed and whether you’d like to come next time!

The 27 speaker 3D surround sound setup was the best we’ve ever had, made possible with the help of recent graduates from Sound, Light and Live Event Technology and Richard and Mark, technicians in Electronics and Sound. Alex Wardle (graduate from Music Tech and Production) also created a video of the event which can be viewed at:

As has been reported around the interweb, OSX Mavericks update stops the GUIs from a number of VST plug-ins functioning correctly (they don’t update when they should). The WigWare plug-ins are also affected by this issue. I have developed a fix, and will try and update all the software when I get a chance. In the mean-time, if there is a plug-in or two that you really need updating first, just let me know!
